Answer:
You need to use the power connector, which is 24-pin, as well as the CPU power connector, which is 4 or 8-pin. And you need the PCI-E power connectors. Now connect the 24-pin part to the motherboard and the 4 to 8 pin CPU power connector. Now insert the Hard drives, SSDs, and the optical drives. And now finally you need to plug the PCI-E power connector to the graphics card. And now double-check that all are plugged correctly, and start the computer. You are done.
Remember that the PCI-E power connector is the high-speed hardware interfaces meant for peripheral devices like the graphics card, SSDs, hard drive, etc. The 24 pin CPU power connector, which is the 24 pin power supply is quite handy to provide the power to the motherboards, and this ensures that the ATX 12V power supply is not required to provide what we know as the auxiliary power cables. Though some of them still need it.
And the 4 pin power supply connector is applied to ensure the supply of +12 VDC to the voltage regulator of the processor.
